TUNELINGEBARREL:

Specification of Letters Patent.

Patented March 6, 1906.

Application 516e April 29, 1905. Serial No. 258,082.

' Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Tumbling-Barrels, of which the following is a specification.

M invention relates to tumblingbarrels, and as for its object to provide a tumblingbarrel which is sim le in construction, yet adapted to fulfil all the requirements demanded of such a barrel in practical use.

It is a further object of my invention to provide a tumbling-barrel which may be easily tilted while being revolved and is capable of being revolved at any angle desired.

With these and other objects in view the present invention' consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed outA in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of kthe invention.

In the drawings, Figure 1 is a perspective view of my improved tumbling-barrel. 2 is a rear vi w of the same. Fig. 3 is a si e view, partly in section; and Fig. 4; is a perspectiveview of a screen-top adapted to be used in connection with the barrel.

Referring to the drawings, 1 is a supportingi`rame, comprising a base portion and upwardly-projecting arms 2 and 3. Pivoted between said arms is a member 4, having a bearing 5 for stub-shaft 6, 'secured to the bottom 7 of barrel 8. This stub-shaft 6 extends through its bearing, and upon its threaded projecting end is screwed a bearing-cap 9. The barrel .8, which may be constructed of sheet metal, wood, or any other suitable material, has preferably the `form of a truncated cone.' The stub-shaft 6 is secured to the botto'm 7 of barrel 8 by a circular plate 9, on the outer periphery of which is formed a circular l rack 10.

The pivoted member 4 is provided with bearin -recesses 11 and 12, which receive the ends o shafts 13V and 14, held in sockets in the upper ends of arms 2 and 3 by set-screws 15. 0n the shaft 14 a sleeve 16 is mounted, upon 5 theinner end of which pinion. 17 is formed, said pinion meshing with the circular rack 10 on the bottom of the barrel. Motion is transmitted to inion 17, and through it to the barrel, by pu ley 18, fixed on sleeve 1G. A loose pulley 19 is journaled on shaft 14.- adjacent tc pulley 18 and is held on said shaft by bearing-nut 20. oted memberl a segmental rack 21 is formed, which meshes with the pinion 22, keyed to Cn the under side of pivshaft 23. This shaft 23, mounted in the lower art of arms 2 and 3 of the frame, has provi ed on its outer end a hand-wheel 24, by which the pinion 22 is turned. A pawl 25 and ratchet 26 are also provided in connection with this shaft to lock' the same in any desired position, said locking means being released by a pedal 27, connected to pawl 25 by rod 28.

In Fig. 3 the 'barrel is shown equipped with a solid cap 29, secured to the end thereof by slots 30 engaging pins 31. Fig. i shows a sieve-cap which may be used to advantage in connection with Vmy invention on some classes' of work..

The operation of my device is as follows: The cap 29 being removed and the barrel being in .a substantially upright position, the

castings or other articles to be polished are `more or less violent agitation be required in order to polish the casting, the barrel will be revolved at a relatively 'gh speed while in the horizontal position. When it is desired lto dump the contents of the barrel, the pawl 1 25 is released by pressing pedal 27. The hand-wheel may then be turned, and with it pinion 22, which is fined on thel same shaft.

The turning of pinion 22 will operate, through the segmental rack 21 and the pivoted member 4l, to which it is attached, to tilt the barrel and empty its contents.

The tumbling-barrel above described is simple in construction, strong, and durable. it may-be operated at any desired angle, will not easily get out of order, and articles being polished can be taken out and inspected without sto )ping the machine.

Having t us daescribed my invention, what l claim as novel,and desire to secure by Letters Patent, is-

'1. ln a tumbling-barrel, the combination with a bifurcated supporting-frame of a pair IOO IOS

rotating said pinion, means for locking said.

pinion anainst movement, a sleeve rotatively mountefupon one of the stub-shafts and havmg apinion formed thereon and an annular rack carried by the barrel with which said pinion meshes.

' 2; In a tumbling-barrel the combination of a supporting-frame, a member having diametrically-disposed recesses therein, a driving-shaft forming a pivot in one of said recesses and a second pivot for said member; a segmental rack integral with the pivoted member, a pinion meshing With said rack to tilt the pivotedmember, a ratchet to revolve said pinion, a loeking-pawl engaging said ratchet, a treadle to release said paWl, abarrel providedI with a stub-shaft journaled in the pivoted member, and means for revolving said pivoted member. f

In testimony whereof I ail'ix my signature in presence of two Witnesses.
